BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention is in the field of travel cups and pertains particularly to methods and apparatus for a reusable travel cup having multiple watertight compartments.

2. Description of Related Art

In the art of reusable travel cups, there are many shapes and styles: cups with handles and screw-on lids, cups made of paper with plastic snap-on tops and various types of holes for straws and for drinking, and cups that are insulated to keep liquids cold or warm.

One detriment to all of these reusable cups is that each one is designed to hold only one type of liquid at a time which must then be cleaned and refilled each time a first liquid is finished and a new liquid is added. Many times, an athlete may go to a gym for a workout and have multiple vitamin, protein, or electrolyte liquids for before, during, and after a workout. This situation causes the athlete to fill and carry multiple cups or bottles to each workout, clean multiple containers after each workout, and overcrowd the athlete's workout bag that is already over-packed with clothes, shoes, and other items.

Therefore, what is clearly needed is a single cup with multiple compartments for storing separate liquids, one unit for space saving, and one adjustable lid for simple easy access to different liquids at different times.

DETAILED DESCRIPTION OF THE INVENTION

In various embodiments described in enabling detail herein, the inventor provides a unique reusable travel cup having multiple accessible storage compartments for containing liquids. One goal of the invention is to provide a travel cup having more than one internal compartment for containing liquids that may each be accessible through uniquely designed openings. Another goal is to provide the travel cup in different sizes and having a different number of liquid containment compartments.

FIG. 1 is an exploded perspective view of a travel cup 100 with multiple compartments for containing liquids. In this embodiment, travel cup 100 includes four basic parts. Travel cup 100 includes a cup base portion 106, an inner lid 104, an outer lid 103, and plug connector 101. In one embodiment, travel cup 100 may be a food grade plastic molded product. In another embodiment, travel cup 100 and basic components introduced above may be fabricated from a metal like food grade stainless steel, or collectively, a combination of materials may be considered, for example, a steel base portion and plastic lids or a plastic form for the base portion with stainless steel lids.

Cup base 106 includes a female thread pattern 107 provided around the inside rim of cup base portion 106. Inner lid 104 includes a male thread pattern provided around the periphery of the interfacing side of the lid. In a preferred embodiment, inner lid 105 is threaded onto cup base portion 106 and forms a watertight seal. In this embodiment, cup base portion 106 has a plurality of compartment partition walls 108 a, 108 b, and 108 c depicted in this embodiment.

In this embodiment, partitions 108 a, 108 b, and 108 c intersect at the center of cup base portion 106 and are angularly arrayed or fixed at one hundred and twenty (120) degrees apart the outer edges of the three partitions 108 a, 108 b, and 108 c conforming to the inside wall of cup base portion 106 in a water tight manner. In this case, three liquid containers of equal volume are formed that may be leveraged to isolate three separate liquids in cup 100 in a watertight manner. Liquids may include but are not limited to energy drinks, vitamin waters, protein shakes, or other desired liquid mixtures.

Inner lid 104 includes a vertical rim of a predisposed height that has an inside diameter just smaller than the outside diameter of outer lid 103. In this way, inner lid 104 provides an annular friction seat for outer lid 103 to rest inside. The upper surface of inner lid 104 and the lower surface outer lid 103 are smooth and flat enough so that outer lid 103 may be turned 360 degrees in either direction while seated within inner lid 104.

Outer lid 103 may include a chamfer 102 provided around the top inside diameter that may provide comfort to the lips of a user drinking from cup 100 and that may reduce spillage of liquids by a user when using a drink opening like drink opening 110 provided through both lids. Outer lid 103 also has at least one drinking straw opening 109. Outer lid 103 further includes an opening 111 substantially at center for plug connector 101. Plug connector 101 is employed to fasten or connect outer lid 103 seated flush with the inner lid 104 and to produce a frictional interface between the lids.

FIG. 2 is a top view of a travel cup analogous to cup 100 of FIG. 1 assembled. In this embodiment travel cup 200 is assembled with outer lid 103 seated down inside inner lid 104. Cup base portion 106 of FIG. 1 is not visible in this view. The inner lid 104 is covered by the rim portion of outer lid 103. It may be assumed in this embodiment that there are three equal volume compartments for containing three separate liquids as described further above relative to cup 100 of FIG. 1.

In this embodiment, inner lid 104 has three straw access openings provided there through and spaced at roughly the same degree pattern as compartment partitions 108 (a-c) giving access through the inner lid to each of the isolated liquids. Straw openings 109 (a-c) are depicted in broken boundary lines to illustrate that they are below the outer lid bottom surface. Outer lid 103 has straw opening 109 placed on an identical bolt circle as straw openings 109 (a-c). Straw opening 109 is rotated off and out of alignment with any of straw openings 109 (a-c), however, a user may rotate outer lid 103 left or right to align straw opening 109 with any of the three straw openings 109 (a-c) placed through the inner lid 104 to gain drinking access by straw to any of the three described liquid compartments.

The bolt circle containing the straw openings is substantially smaller than a bolt circle containing drink openings depicted herein as drink openings 110 a, 110 b, and 110 c placed through inner lid 104. In this embodiment, a drink opening 110 in outer lid 103 is rotated to be in alignment with drink opening 110 a placed through inner lid 104 giving a user drinking access to one of the three separate liquid compartments within the body of the cup. The bolt circles containing the drinking openings and the straw openings are concentric to each other and to the center of the cup occupied by connector plug 101.

Drink openings 110(a-c) in inner cup 104 are collectively located proximal to the outside peripheral edge the underlying surface of inner cup 104. In this embodiment, they are spaced 120 degrees apart like straw openings 109 (a-c) and the partitioned liquid compartments identified in FIG. 1 above. The patterns are offset relative to the straw access openings 109(a-c) and openings 110(a-c) so that just one of any drink opening or straw opening may be accessed by the user at any one time by correctly rotating the outer lid to align the desired openings for the desired liquid compartment. Therefore, in this view, drinking opening 110 in outer lid 103 is aligned over drinking opening 110 a in inner lid 104 while drink openings 110 b and 110 c are in a closed or non-aligned position.

A rotation of 120 degrees of outer lid 103 in a clockwise direction will open another drink opening 110 (110 b) or counterclockwise will open 110 (110 c). A rotation of 60 degrees in a clockwise direction will open a straw access opening 109 (109 b) or counterclockwise will open straw access opening 109 (109 c). Straw access opening 109 a and drink opening 110 a of inner lid 104 provide access to the same isolated or partitioned liquid compartment, straw access opening 109 b and drink opening 110 b provide access to a second liquid compartment of the same volume, and straw access opening 109 c and drink opening 110 c to a third liquid compartment of the same volume. The open volume of liquid is determined by the rotation of outer lid 103 and matching a hole opening on outer lid 103 with a like hole opening on inner lid 104.

Plug connector 101 is frictionally loose enough so that outer lid 103 may rotate inside of inner lid 104 but frictionally snug so that there is no leakage between the lids or an inadvertent disconnect between outer lid 103 and inner lid 104 when in use or stored. In one embodiment, the frictional connector plug 101 is adjustable to produce more or less friction force against the inner and outer lids. It is also important to note that there are any number of ways the inventor may provide markings on the outer lid 103 or inner lid 104 to distinguish each separate volume section for the user.

FIG. 3 is an exploded perspective of a travel cup 300 with multiple compartments for containing liquids according to another embodiment of the invention. Cup 300 has a cup base portion 306 that is divided into two equal volume liquid compartments by a single partition 308. Like cup 100 and 200, travel cup 300 has a female thread pattern 307 around the inside top ring of the cup that matches an external male tread pattern 305 on the outer lower periphery of an inner lid 304 for purpose of assembly.

Outer lid 304 includes a chamfer 302, a drink opening 310, a straw access opening 309, and an opening for plug connector 311, which are all analogous to the descriptions given of the corresponding elements in travel cup 100, lid 104 of FIG. 1. A plug connector 301 is provided to connect outer lid 303 to inner lid 304 when assembled.

In this embodiment, the openings are numbered in the inner lid to one straw opening to each liquid compartment and on drink opening to each liquid compartment. A user rotation of 180 degrees of the outer lid 303 clockwise or counter-clockwise aligns a drink opening 310, depicted here aligned with one of the drink openings in the inner lid 304 with the other drink opening in inner lid 304 or the opposite liquid compartment. From this position the user may rotate the outer lid 303 ninety-degrees clockwise or counterclockwise to align straw opening 309 with either straw openings in the inner lid 304. Connector plug 301 and partition 308 function as their counterparts plug connector 101 and partitions 108(a-c) of FIG. 1.

FIG. 4 is a top view of a travel cup 400 analogous to travel cup 300 of FIG. 3 assembled. Outer lid 303 is situated above inner lid 304 so only the outer lip of inner lid 304 is visible. Outer lid 303 is connected to inner lid 304 by plug connector 301.

Straw access openings 309 a and 309 b are shown in the off position, and, when outer lid 304 is rotated either direction 90 degrees, straw access opening 309 may aligned with one of the straw access openings 309 a or 309 b.

Drink opening 310 (310 a) is shown in the open position. A rotation of outer lid 303 of 90 degrees counterclockwise will close drink opening 310 (310 a) to a compartment, or counterclockwise rotation will open straw access opening 309 (309) in a second volume. A rotation of outer lid 303 of 180 degrees will also open a new drink opening 310 (310 b) in a second volume on the opposite side of cup assembly 400 and allow access for drinking out of a second volume. In this embodiment, straw access openings 309 a and 309 b are on opposite sides of the same diameter line, and drink openings 310 a and 310 b are also opposite each other. The partition 308 (not visible) runs diagonally in this view.

Variations in other embodiments may include but are not limited to having unequal liquid compartment volumes. In one embodiment, more than three liquid compartments may be provided within the cup base portion. In one embodiment openings through the outer and inner lids may vary in shape and diameter and pattern placement or configuration without departing from the spirit and scope of the present invention. In one embodiment, an accessory like a pour spout may be provided as a plastic molded part and snapped or pressed into an opening for liquid poring purposes.
